Ideal for large and enterprise businesses, is a highly reliable, flexible and scalable storage system for Microsoft Exchange Server, VMware, databases and other business applications. It also provides an optimal choice for tiered and standalone storage, consolidation, business continuity, data replication, backup and archiving.

3 EXECUTIVE SUMMARY Page 3 of 6 Summary of Results SPC-1 Results Tested Storage Configuration (TSC) Name: Metric SPC-1 IOPS 89, Reported Result SPC-1 Price-Performance Total ASU Capacity Data Protection Level $6.71/SPC-1 IOPS 15, GB Mirroring Total TSC Price (including three-year maintenance) $600,581 SPC-1 IOPS represents the maximum I/O Request Throughput at the 100% load point. Total ASU (Application Storage Unit) Capacity represents the total storage capacity read and written in the course of executing the SPC-1 benchmark. A Data Protection Level of Mirroring configures two or more identical copies of user data. Storage Capacities and Relationships The following diagram documents the various storage capacities, used in this benchmark, and their relationships. Application Storage Unit (ASU) Capacity 15, GB ASU 1 7, GB ASU 2 7, GB 1 Logical Volume 1 Logical Volume 1 Logical Volume Addressable Storage Capacity 15, GB ASU 3 1, GB Unused Storage 7, GB Metadata/Overhead 1, GB Configured Storage Capacity 50, GB Physical Storage Capacity 51, GB Data Protection (Mirroring) 25, GB (includes 1, GB of Metadata/Overhead and 7, GB of Unused Storage) Global Storage Overhead GB Unused Storage GB
